Precision Availability Metrics for Services Governed by Service Level Objectives
RFC 9544, “Precision Availability Metrics for Services Governed by Service Level Objectives”, is an Informational document published in March 2024 by G. Mirsky, J. Halpern, X. Min, A. Clemm, J. Strassner, J. François. The canonical text is published by the RFC Editor.
Abstract
This document defines a set of metrics for networking services with performance requirements expressed as Service Level Objectives (SLOs). These metrics, referred to as "Precision Availability Metrics (PAMs)", are useful for defining and monitoring SLOs. For example, PAMs can be used by providers and/or customers of an RFC 9543 Network Slice Service to assess whether the service is provided in compliance with its defined SLOs.
